SPRING-HINGE SPECIFICATION forming part of Letters Patent No. 655,812, dated August 14, 1900.

Application filed February 27, 1900. Serial No. 6,752. (No model.)

To all whom t may concern.-

' Be it known that we, ABRAHAM L. STUMP and FRANCIS BRUGKER, citizens of the United States, residing at Shelby, Richland county, Ohio, have invented certain new and useful Improvements in Double Acting Spring- Hinges, of which the following is a specication.

' Our invention relates to improvements in double-acting spring-hinges, and is designed as an improvement upon the spring-hinge patented to us under date of November 14, 1899, No. 637,218.

The objects of the invention are to render the hinge' more easily applied, to render it more easy in action, to provide for the accurate alinement of the door after it has been hung without necessitating its removal for this purpose, and, lastly, to provide means by which when the door is swung back to its fullest extent it will be automatically retained in this position. 4

To these ends the invention consists in the details of construction hereinafter described, and particularly pointed out in the claims.

We have illustrated the invention in the accompanying drawings, in which- Eigure l is a central longitudinal section. Fig. 2 is a detail horizontal section showing the bearing-pins- Fig. 3 is a similar view of a modification. Fig. 4 is a side elevation. Fig. 5 is a detail crosssectional view on the line 7 7, Fig. 1, viewed from below with the door swung back. Fig. 6 is a detail plan view.

Referring to the drawings, d represents the spring-barrel, which is preferably formed in? tegral with the attaching plate or plates a, which are secured directly to the face of the door-jamb, (indicated at A,) said jamb being mortised or bored to receive the spring-barrel.

b indicates the socket-plate, which is secured to the door Bin a suitable manner, as by screws and also by face-plates, as hereinafter described.

The socket-plate b has a hinge-pin g', which engages an opening in the front extension d of the spring-barrel, this opening extending to the side of the extension and being closed by a projection czfrom the face-plate c. Nit-hin the spring-barrel is located a'slide e, which has its rear end turned upwardly, while its forward end e projects downwardly through an opening in the barrel. This slide may rest directly on the bottom of the barrel; but we find it advantageous to interpose an antifriction-roller d2, as indicated in Fig. 1, thereby preventing binding of the slide and rendering the action of the spring easier. The springt bears at one end against the upturned end of the slide and at its other end against a threaded washer Z, which receives the screw k, Which bears against the plate h and has a contracted head extending through the plate, 'whereby it may be rotated to adjust the tension of the spring hereinbefore referred to.

In order to render the action of the spring more easy, we provide the socket-plate b with two projecting pins ff, which are provided with antifriction-collars f' f', which are adapted to contact with the downwardly-extending flange or rib e/ on the front end of the slide e, so that as the door is swung in one direction or the other these pins and rollers withdraw the slide outward against the tension of the spring, which thus tends to return the door to normal position.

We prefer to form a socket or recess in the socket-plate b, into which We place a plate b2, which carries the said pins and antifrictionrollers, and this plate may be adjusted by setscrews b3, threaded into the socket-plate and bearing against the plate b2. By this means after the door has been hung it may be adjusted to cause it to occupy the proper position when at rest or to drawit close to the j amb without taking it down and rehanging it.

It is desirable to .provide means for automatically holding t-he door open when swung to the limit of its open position, and for this purpose we provide a rabbeted portion e2 centrally of the downwardly-projecting Iiange or portion e/ of the slide e, as shown in Fig. 5, so that when the door lis swung back beyond a right angle, as shown in said gure, the proj ection or roller will rest against the shoulder formed by said rabbet or recess, and the projection being then substantially on line with the pivot on which the door swings it will be held open.

We prefer to cover the joint between the socket-plate b and the door by ornamental face plates D, and these face-plates may IOO either` terminate flush with the inn'er edges of the socket-plate or, if desired, may extend over the edge of the door and meet at the center, as indicated at 9c, whereby the socketplate Will be completely covered up and may be made of cheaper metal.

In hanging doors with double-acting hinges it is generally customary to place a strip against the j amb to which the hinge is secured to provide the necessary clearance for the door.` With our construction we lind this unnecessary, and we secure the socket-plate directly to the face of the jamb, as shown in the drawings, and as this sets the door oft a little from the jamb we provide an ornamental molding A', which we secure against the j amb on each side, making a close joint.

Having thus described our invention, what we claim isy l. A spring-hinge comprising a plate having a socket, a second plate having a hollow portion pivoted within the socket, a slide within the hollow portion having a flanged outer end, a spring exerting tension on said slide, and antifriction projections carried by said first named plate coacting with said flanged end of the slide, substantially as described.

2. A spring-hinge comprising a plate having a socket, a second plate having a hollow portion pivoted within the socket, a slide within the hollow portion having a flanged outer end, a spring exerting tension on said slide, and projections carried by said firstnamed plate coacting with said flanged end of the slide, said Han ge having a recessed por-V tion adapted to receive the projections when the door is swung to a predetermined limit to hold it in its opened position, substantially as described.

3. A spring-hinge comprising a plate having a socket, a second plate having a hollow portion pivoted within the socket, a slide within the hollow portion, a spring exerting tension on said slide, a movable projection carried by said first-named plate adapted to coact with said slide to move the same, and means for adjusting said projection, substantially as described.

4. A spring-hinge comprising a plate having a socket, a second plate having a hollow portion pivoted within the socket, a slide within the hollow portion, a spring acting on said slide, a plate carried by said socket-plate having movable projections acting with said slide, and means for adjusting said plate to move said projections, substantially as described.

5. A spring-hinge comprising a plate having a socket, a second plate having a hollow portion pivoted within the socket, a slide within the hollow portion having an operating connection with the socket-plate, a spring acting on said slide and an antitriction-bearing for said slide, substantially as described.

6. A spring-hinge comprising a plate having a socket, a second plate having a hollow portion pivoted within the socket, a slide within the hollow portion having a flanged outer end, an antifriction-roller between the slide and bottom of said hollow portion, a spring exerting tension on said slide, and a projection carried by said first-named plate coacting with said flanged end of the slide.

In testimony whereof we affix our signatures in presence of two witnesses.
